The interface goes between the power cable and Aurora, using Molex 3 pin connectors. The interface has a 3.5mm stereo audio jack, so you can connect any audio output. There’s a potentiometer to adjust the sensitivity level as well.
Aurora 12 bar, Aurora 9×18 mk2 and Aurora 18×18 have audio or “color organ” modes, which you can select by either pushing the on board button or using a remote control (remote not on Aurora 12 bar).

I discovered a bug that prevents start up at the power on. The condition is relatively rare, but if your Aurora 9×18 mk2 or Aurora 18×18 is suffering from occasional lookup at the power up, please reprogram the PIC with the updated firmware.

This firmware (version 1.4) is also revised to keep the speed change setting in the EEPROM (note: speed adjustment is only possible via IR remote), so that your set speed will be restored after power off/on.

Please let me know if there are any issues with this updated version.

(The original Aurora 9×18 video)

The kit includes everything you need to build Aurora 9×18 mk2, plus mounting screws & nuts. Those screws can also help you when you solder in the LEDs, by giving the PCB a lift off the working surface.

The smallest SMD parts are 0603 size, which is quite tiny. Naturally it’s very easy to lose them while assembling. Since it’s not much fun having to buy those little parts because you lose them, I’m including a few extras for all 0603 size parts. There are a few extra LEDs included as well. Hopefully you won’t have to stop the assembly because you’ve lost a few parts.

- View the soldering/assembly guide.

IMPORTANT: You need a compatible PIC programmer such as PICkit 3, ICD2/3, etc. to program the PIC. (PICkit 2 does not support the newer PICs used on those Auroras.) If you don’t have access to program the PIC, you can choose “programmed” option for additional $5. The PIC IC will be soldered to the PCB in order to be programmed.

The interface goes between the power cable and Aurora, using Molex 3 pin connectors. The interface has a 3.5mm stereo audio jack, so you can connect any audio output. There’s a thumb-wheel style trim pot to adjust the sensitivity level as well.
New Aurora 9×18 mk2 and Aurora 18×18 have audio or “color organ” modes, which you can select by either pushing the on board button or using a remote control.

I have finalized the designs of new Aurora 9×18 mk2 and Aurora 18×18. Developing these things takes a lot of effort, time and of course, money.
I really want to make those Aurora’s available as kits, however I need a small capital to do so quickly. Otherwise I’d have to wait.

So here’s the deal, I will offer those kits at 20% discount until I have them shipping. Once the kits are in, the final prices will be $179 for Aurora 9×18, and $289 for Aurora 18×18. (At the worst case where I could not deliver those kits, your money will be refunded. PayPal will offer protection against non-delivery, so rest assured.)
I’m really hoping that with your help, these kits will be shipping within 4 weeks.

IMPORTANT: Like all other kits I sell, PIC microcontrollers are not preprogrammed. You need a compatible PIC programmer such as PICkit 3, ICD2/3, etc. to program the PIC. (PICkit 2 does not support the newer PICs used on those Aurora’s.) This is due to the fact that surface mount PIC need to be soldered to a PCB before being programmed.
